Pinus pinea is native to the Mediterranean region, with its hot, dry summers and cool, moist winters. It is not a very cold-hardy plant, being able to tolerate short periods with temperatures down to around -10°c when fully dormant[2]. This species can tolerate occasional lows to about -18°c[3]. Although sometimes thought to be somewhat tender in temperate regions, it is perfectly hardy as far north as south-east Scotland[4]. Pine species in general require a sunny position if they are to grow well and, whilst the different species have their own soil preferences, most will thrive in a light well-drained sandy or gravelly loam[5, 6]. Dislikes poorly drained moorland soils[5] and shady positions[3]. Established plants tolerate drought[7]. Succeeds in a chalky soil[6]. The trees transplant very badly if they are allowed to stay in one position for more than 2 years[4]. The Italian stone pine is extensively planted for its edible seeds in Europe[8, 7]. . These are harvested while still inside the closed cones, which are pulled down from the trees with hooked poles; the cones open when heated. For this purpose lower tree crowns are favoured, which is accomplished by keeping the canopy open[9]. Millions of kilogrammes of seeds or 'pine kernels' are harvested in the Mediterranean countries each year[9]. The variety 'Fragilis' has thin shelled seeds and is the form most widely cultivated[7]. This is usually a short-lived tree, rarely surviving for much more than 100 years[4]. Trees take between 10 and 20 years to begin producing cones from seed[3]. One of our plants, growing in Cornwall, southwest england, produced its first young female cone when 7 years old, though this did not mature because it was not fertilised[PFAF]. A 20 year old plant at Kew Gardens in London was about 4.5 metres tall with a number of trunks and had more than 15 mature cones[PFAF]. A very old specimen at Kew was carrying lots of 1st and 2nd year cones in July 1996[PFAF]. Mature trees have a thick, fire resistant bark[9]. The broad ovoid to globose seed cones are 8 - 15cm long, 5 - 12cm wide. The massive cones take three years to mature and can remain on the tree for several years without opening. The seeds are nearly wingless and are dispersed by birds (also eaten by rodents) or may scatter after fire has burned off the undergrowth and its heat assisted in opening the cones[8, 9]. This is one of several species of pine that have a mutualistic relationship with species of birds in the family Corvidae (in this case Jays and Nutcrackers) to disperse its seed. The birds have powerfull beaks which enable them to extricate the seeds and crack the shells. They store many of the seeds at some distance from the parent plant - some of these seeds never get eaten and can germinate and grow into new trees[2]. Plants are strongly outbreeding, self-fertilized seed usually grows poorly[7]. This species does not hybridize with other members of this genus[10]. Leaf secretions inhibit the germination of seeds, thereby reducing the amount of plants that can grow under the trees[11]. Plants in this genus are notably susceptible to honey fungus[7].

Propagation

It is best to sow the seed in individual pots in a cold frame as soon as it is ripe if this is possible otherwise in late winter. A short stratification of 6 weeks at 4°c can improve the germination of stored seed[12]. Plant seedlings out into their permanent positions as soon as possible and protect them for their first winter or two[6]. Plants have a very sparse root system and the sooner they are planted into their permanent positions the better they will grow[PFAF]. Trees should be planted into their permanent positions when they are quite small, between 30 and 90cm[7]. We actually plant them out when they are about 5 - 10cm tall. So long as they are given a very good weed-excluding mulch they establish very well[PFAF]. Larger trees will check badly and hardly put on any growth for several years. This also badly affects root development and wind resistance[7]. Cuttings. This method only works when taken from very young trees less than 10 years old. Use single leaf fascicles with the base of the short shoot. Disbudding the shoots some weeks before taking the cuttings can help. Cuttings are normally slow to grow away[8].
